ZEBINA EASTMAN, OF CHICAGO, ILLINOIS Letters Patent No. 91,105, dated June 8, 1869.

TIMPROVED STREET-CAR.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, ZEBINA EASTMAN, of Ghicago, in the county of Cook, in the State of Illinois, at present residing abroad as the United States consul at Bristol, have invented a new and useful improvement in the form and construction of the bodies of horsecars, and carriages, steam railway-cars, and carriages for common roads; and I do hereby declare the following to be a full, clear, and correct description of the nature, construction, and operation of the same, reference being had to the accompanying drawings, which are made'part of this specification.

Figure 1 is a side elevation view of one of these cars. 7

Figure 2 is a ground plan of the same, showing the manner oil seating, and division of the car, by a succession of rings or circles, forming upright tubes, for the separate apartments.

Figure 3 shows the manner of construction, with iron, or in a combination of wood and iron, with light angle-iron for corners, and T (tee) ironfor the side supports or frame, and the panels of wood or sheetiron, for filling in the side surface or spaces.

Figure 4 shows the manner of filling in the panel,

and strengthening the frame-work to the panel with cross-pieces and braces of strap-iron through the panels.

Figure 5 is an exhibition of the same, for supporting the sides or long panels, under the seats and windows. The several letters of reference indicate correspond ing parts in all the figures.

This invention is particularly adapted for the construction of car-bodies, with my radial or oscillating axles, secured in other patents; and in constructing the bodies in this manner, I first find the centres for my tubular forms by getting the positions of the kingbolts on the two axles; I then strike circles for the plan of construction from the centre of these kingbolts, to the size I m'sh to make my car, large or small, having the outer surfaces of these tubes toicover the wheels and ends of axles, and form the seats over the wheels in a circular form, indicated by the oscillating movements-of the wheels when moving in curves.

To swell and strengthen the sides of the car, I strike another circle for the centre of the car, half way between the two centre points of the other circles. I strike the iniddle circle or tube, of larger size, by one foot, more or less, and then contract the circle, or elongate it to an oval form, as may be necessary to accommodate it to the length of the car, having the edges of the several tubes meet at the openings or door-ways between the circles in the common aisle or passage- The appearance of the inside is that of three pavilions, passengers sitting in a circle, with two arched doors at each end, and at each side corresponding arched windows. This is seen in the two figs. 1 and 2.

a is the common passage.

b b are the circular seats, inside.

' c c are spaces between the tubes, which may be util izcd as boxes for carrying luggage. 1

(Z d are the outside-circle seats, under the awning of the roof.

c e are rotary seats for driver and conductor, the reversal of which alternately form drivers seator conductors seat, as the car may run either way.

Figs. 3, 4, and 5 are for the more particular descrip tion of the manner of constructing these cars, so as to combine strength with great lightness; they are to be made mostly with thin and light iron, and generally combined with thin wooden panels.

a, shows the angle-iron at the corners.

I), T-iron, in that part where the form of the framework requires it.

c r: are the rivets, which bolt the iron frame, panels, and strap-iron together.

(l d are the wooden panels or sides.

e e e are pieces of strap-iron, which are bolted through the panels to the iron frame.

They thus act as ties and braces to bind the whole together, and stiffening it, giving the car great firmness and strength, while being very light in material.

The shapes are all tubular or arched, there being no corners or straight lines, except at the bottom, and the combination has all the strength of the arch or tube.

ff are half rounds or mouldings, as finishing-pieces, put on as the last finish of the car, and which may be removed in refitting, made of mahogany or other ornamental wood, which is to fit over the tail part of \Vitnesscs M. J. EASTMAN, E. HooD.
